Model for phase transition and low-temperature phase of tetraselenafulvalene-tetracyanoquinodimethane

Abstract

The properties of TSeF-TCNQ are contrasted with the properties of its isostructural analogue TTF-TCNQ. Despite the obvious similarities between these two systems, they exhibit a number of remarkable differences. A Ginzburg-Landau model is proposed that appears to explain a number of these differences. © 1977.
